Geology of the Machattie 4-Mile Sheet Area, Queensland, 1960

1960 mapping of the Machattie 4-mile Sheet area in western Queensland established a sequence of at least 2750 feet of Cretaceous rocks. The data, sourced from Geoscience Australia, describes the geology of the western Great Artesian Basin, including potential petroleum source and reservoir rocks. No economic mineral deposits were found in the area.

Use Cases

• Model groundwater aquifers based on described Cretaceous rock sequences and impermeable cap layers.
• Assess petroleum potential based on identified Lower Cretaceous shale source rocks and sandstone reservoir rocks.
• Analyze regional geological structures based on the described north-east trending structure.
• Correlate stratigraphy with adjacent areas based on references to the Boulia and Springvale 4-mile Sheet areas.

Strengths

• Based on surface mapping and examination of water bore logs from 11 artesian and 2 sub-artesian bores.
• Provides specific geological measurements, including a Cretaceous rock sequence of at least 2750 feet and up to 55 feet of Tertiary sediments.
• Identifies specific geological features relevant to resource exploration, such as the Wilgunya Formation and Longsight Sandstone.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is from a 1960 survey; freshness should be verified for contemporary applications.
